Application filed September 12, 1913.

To all whom, it may con/cern Be it known that I, F nnnnln K. MARTIN, acitizen of the United States, residing at Chelsea, in the county oiRogers and State ott Oklahoma, have invented new and useful Improvementsin Oil-Burners, ot' which the following is a specification.

This invention is an improved oil burner especially adapted for burningcrude pctroleum being also adapted for bluning other liquidhydrocarbons, the object oit the invention being to provide an improvedburner of this kind which is extremely cheap and simple, the parts ofwhich may be assembled and disassembled and may be kept clean and inorder.

The invention consi ts in the construction, combination and arrangementof devices hereinafter described and claimed.

In the accompanying drawing: Figure l is a vertical longitiulinalcentralA sectional view of a burner constructed in accordance with myinvention. Fig. 2 is a vertical transverse view of the same on the planeindicated by the line a-a of F ig. l.

In accordance with my invention I provide an oil supply duct l, which isa straight pipe and is provided at its outer end with an intake tubulararm 2 arranged at right angles thereto and to which an oil supply pipefrom a si'litable reservoir is in practice connected. A steam jet pipe 3is arranged in the oil supply duct 2, concentrically thereof and passesthrough an opening in the arm 2. This steam jet pipe extends about haltway through the oil supply duct l.

A mixer #L which is tubular in form and is of greater diameter than theoil supply duct has a reduced inner end 5 provided with an openingthrough which the said oil supply duct extends and also has a reducedouter end 6 formed with a nozzle or jet tip 7. The mixer is slidably.fitted on the oil supply duct and may be adjusted longitudinallythereon and secured in adjusted position by means oit' a clamping screw8. In the sides of the mixing tube l at points about midway between theends thereof is a series of Patented Mar. 10, 1914.

Serial No. 789,501.

air inlet openings t). A cover sleeve 10 is iitted on the outer side ofthe said mixer L and may be turned or moved to close the air intakeopenings to any desired extent.

In the operation of my improved burner steam trom a boiler is suppliedto the steam jet pipe 3 and as it passes through the oil intake duct 2creates the partial vacuum therein and hence causes oil as well as steamto be discharged into the mixer and also causes the oil to be atomized.Air is admittcd to the mixer through the openings 9 and becomes`coi'inningled with the atomized oil to render the latter' highlycombustible and as the oil, air and steam issue from the mixer throughthe jet tip 7 the said mixture is burned in a clear flame and withoutlsmoke. The heat caused by the [lame and Sm'rounding the burner in thefurnace or other place where the burner is used also causes the burnerto act as a retort and vaporize and promote the combustion ot the oil.

Having thus described my invention, ,li claim:

An oil burner of the class described con prising an oil supply ducthaving a teed arm at .right angles thereto, a steam jet pipe arrangedctimcentrically in said oil supply duct and extending through an openingin one side oi the feed arm thereo'", a tubular mixer of greaterdiameter than the oil supply duct and in which the latter is arranged,said mixer having a reduced inner end providing an opening through whichthe oil supply duct extends and being dctachably .fitted on said oilsupply duct and being further provided with a reduced outer end providedwith a jet tip, the mixer heng further provided with air inlet openingsat a point int-,erinediate its ends and means to vary the ell'ectivcarea ol' said air inlet openings.

In testimony whereo't l ai'lix my signature in presence ot twowitnesses.
